Tonight’s new episode of ABC’s soapy indulgence Revenge is titled “Legacy” for a good reason – it delves into the history of lead character Emily (Emily Van Camp) as it relates to the folks she’s currently trying to take down in the Hamptons. The official logline from ABC describes tonight’s episode as “the genesis of Amanda’s ultimate plan to bring justice from her father.” But we’ll let series creator and executive producer Mike Kelley explain: “It’s sort of one from the archives, one from the Revenge archives,” he says. “I wouldn’t call it a flashback episode, as much as an archival episode. It’s a bit of a love letter to fans.”

Specifically, the episode digs into a party that we glimpsed early in the season via a photo that the adulterous (and currently MIA) Lydia (Amber Valletta) had threatened to bring to light. The photo showed a disguised Emily working at a party, serving champagne, with her various nemeses in the foreground. “It’s an episode that takes place on New Year’s Eve 2002, picking up from that photograph, with Emily serving champagne and standing behind Victoria [Madeleine Stowe] and Lydia,” explains Kelley. “So the entire episode is about that party and how Emily first came to meet the people who destroyed her father. It reminds us how she got into this and why.”

And here’s a shocker: The episode will bring back one character who will likely not last that much longer. “We bring back all of these characters that we’ve taken down over the season,” Kelley continues. “At least one of those characters is going to resurface in the season’s end-run of episodes, and that character will pay the ultimate price for coming up against Emily. I won’t say which one, but out of all the conspirators, someone is going to fall.”
